A nurse is providing vehicle safety education to the parents of a premature newborn.
Which of the following statements should the nurse include in the teaching?
"Your newborn will need to have a car seat test prior to discharge.”.
"Position the retainer clip at the level of your newborn's abdomen.”.
"Place your newborn in a front-facing car seat in the back seat of the vehicle.”.
"You should secure your newborn's car seat at a 60-degree angle.”.
The Correct Answer is A
Choice A rationale
Premature newborns have immature respiratory and neurological systems, making them vulnerable to respiratory compromise and apnea in a car seat. A car seat test prior to discharge assesses their ability to maintain adequate oxygenation and heart rate while positioned in the car seat for a prolonged period, ensuring safety.
Choice B rationale
The retainer clip should be positioned at the level of the newborn's armpits, not the abdomen. Proper placement at the armpit level ensures that the harness straps are snug over the shoulders and chest, effectively restraining the infant and preventing ejection in the event of a collision, optimizing crash protection.
Choice C rationale
Newborns, especially premature ones, must always be placed in a rear-facing car seat in the back seat of the vehicle. Rear-facing provides optimal support for the newborn's fragile head, neck, and spine, distributing crash forces over the entire back and significantly reducing the risk of severe injuries in a collision.
Choice D rationale
The recommended angle for a rear-facing car seat is typically between 30 to 45 degrees, depending on the specific car seat model, not 60 degrees. This recline angle is crucial to prevent the newborn's head from falling forward and compromising their airway, which is particularly critical for a premature infant with underdeveloped neck control. .

Correct Answer is ["A","C","D"]
Explanation
Choice A rationale
Vacuum-assisted delivery increases the risk of postpartum hemorrhage due to potential trauma to the birth canal and uterine atony caused by prolonged pressure or rapid extraction. The vacuum device can bruise the cervix, vagina, or perineum, leading to lacerations that bleed excessively. It can also overstretch uterine muscles, impairing their ability to contract effectively after birth.
Choice B rationale
A newborn weight of 2.948 kg (6 lb 8 oz) is within the normal weight range for a full-term infant. This weight does not typically pose an increased risk for postpartum hemorrhage. Larger infants (macrosomia, generally > 4 kg) are associated with higher risks due to increased uterine stretching and potential for prolonged labor or birth trauma.
Choice C rationale
Labor induction with oxytocin significantly increases the risk for postpartum hemorrhage, particularly due to uterine atony. Prolonged oxytocin administration can lead to desensitization of myometrial receptors, reducing the uterus's ability to contract effectively postpartum. This impaired contractility prevents compression of uterine blood vessels, resulting in excessive bleeding.
Choice D rationale
A history of uterine atony is a substantial risk factor for recurrent postpartum hemorrhage. Uterine atony is the most common cause of postpartum hemorrhage, accounting for a majority of cases. A prior history indicates a predisposition for the uterine musculature to fail in contracting adequately after birth, leading to uncontrolled blood loss.
Choice E rationale
A history of human papillomavirus (HPV) infection does not directly increase the risk of postpartum hemorrhage. HPV is a viral infection that primarily affects epithelial cells, often leading to genital warts or cervical dysplasia. It does not inherently alter uterine contractility, coagulation factors, or predispose to abnormal placental implantation, which are direct causes of hemorrhage.
Correct Answer is D
Explanation
Choice A rationale
The specific volume of formula for gavage feeding a newborn, such as 20 mL, depends on the newborn's weight, gestational age, and clinical condition. A blanket recommendation of 20 mL without this individualized assessment is inappropriate and could lead to over or underfeeding, impacting growth and gastrointestinal tolerance.
Choice B rationale
Placing a newborn in a supine position immediately after gavage feedings increases the risk of aspiration, especially for infants with immature swallowing reflexes or reflux. The newborn should be positioned on their right side or semi-Fowler's position to facilitate gastric emptying and minimize aspiration risk.
Choice C rationale
While cluster feeding (multiple feedings close together) is a natural pattern for some breastfed infants, for gavage feeding, regular, scheduled intervals are typically maintained to ensure consistent nutrient delivery and proper digestion, especially in newborns who are medically fragile. Cluster feeding is not a standard gavage feeding practice.
Choice D rationale
Nonnutritive sucking (e.g., pacifier use) during gavage feedings is crucial for promoting oral motor development and associating the feeling of fullness with sucking. This helps prevent oral aversion and prepares the newborn for eventual oral feeding, stimulating gastric secretions and improving digestion.
